  • What is polyamine used for?
  • Polyamine is a low molecular weight cationic water-soluble liquid polymer, which can be used as coagulant in solid-liquid separation process in water treatment industry, charge neutralizer and adhesive control agent in paper industry.
  • How do polyamine flocculants help in wastewater treatment?
  • Nutrient Removal: In wastewater treatment, polyamine flocculants can aid in the removal of nutrients, such as phosphorus and nitrogen compounds. These nutrients can contribute to excessive algal growth and eutrophication in receiving water bodies.
  • Can polyamine be used for effluent treatment & desludging?
  • Lot of research work have been carried out on application of polyamine for effluent treatment, demulsification and desludging for different industries i.e. pulp & paper, mining, pharmaceutical, textile, oil & gas (Yue et al. 2008; Wang et al. 2009; Karhu et al. 2014; Gupta et al. 2014, 2016; Sun et al. 2016; Wu et al. 2018).
  • Does pH affect polyamine coagulant efficacy?
  • Figure 8 shows the effect of pH on efficacy of polyamine as well as conventional coagulant. High color removal efficiency was observed under acidic and low alkaline conditions. pKa of the sulfonic acid group is under 2.0, where as those of azo group is under 9.0.
